Replacing Octopus Furnace??

[James Konvalinka]

Hey,

I am wondering if anyone has some experience in replacing an old octopus Furnace with a forced air furnace? I am looking at purchasing a duplex that currently has an old school octopus furnace that has been converted to burn natural gas and I have no idea what it would cost to convert this to forced air or what the process would even be. I am planning on reaching out to some local HVAC contractors but I was wondering if anyone on BP has done this before and could shed some light on what I might be getting myself into. 

Cheers!
